that a cool game
Origamer2020-08-291 point
This game was Classic, when I played it just after release. A few people complained about the dislocated type wrist action when operating placed guns and maneuvering objects, but the story is great and the dinosaur AI was awesome, as I remember and had me proper scared at the time (those Velociraptors looked so intelligent and cunning).
If you can look past the age and somehow get immersed you are in for a good game.

Runs great if you run as administrator and you open the setup folder and click setup95.exe. (Don't install directx)
PeterNeal2020-07-150 point
You can bypass the copyprotection by copying the content of the ISO to a folder, running regedit and changing Data Drive from E:/ to that folder
Crazyhuntaholic2020-07-080 point
Sorry, make sure to go in the setup folder and click setup95.exe

IS IT A VIRUS?
TheRighteousMan2020-01-232 points
I've beaten this game so many times and it's disappointing every time. Usually 5 or so years go by... I'm feeling nostalgic, install it, start playing, and it's inevitably worse than I remember. That said I still like it and I'll probably play through it again soon.

Mac users, use WINE or Bootcamp or anything else to run the windows game on your Mac though make sure to install ATX mod.
Same for Linux users, it should work fine under WINE with ATX.

I was in love with this game when it first came out. I've played through a few times.
Athanasius2018-07-272 points
I confess: I love this game! Yes, it's buggy and difficult to play - but it's one of the most original games I've ever played. Stranded on a giant island that's inhabitet by - you guess it - prehistoric monstrosities, you explore the remnants of a great vision: A Jurassic Park. What first comes to my mind if I think on this game: It's huge, open world and manages to evok a feeling of loneliness and desperation. The dinosaurs you'll encounter follow their different behaviours and even if they are not of the most intelligent kind, they sometimes feel menacingly real. The whole experience manages to suck you in the game's world - nothing detracts you from the illusion of seeing through the eyes of your alter ego, even your health indicator is implemented in the gameworld in a very clever way. What made this game way ahead of its time was the physical system it features - while it is lackluster, it still is fascinating to experiment with. You move around crates to climb on a roof otherwise out of reach, you move planks to 'repair' a damaged bridge, you throw objects, stones or even emptied weapons on your enemies. The fighting system needs some practice, but you'll learn it fast. There are so many different things to tell about this game that could have been a masterpiece. For me it's a great game with all its flaws. Just be sure to install the ATX-Mod, it enhances the game and kills some of the nastier bugs.
Good luck out there!

| To do: There's a lot more T-Script stuff to document. |
Trespasser's T-Script is the heart and soul of the engine. These scripts help objects, dinosaurs, and triggers work. Because of the rushed development, many went unused. Others were removed due to bugs such as the dinosaur emotions.
- 2Unused Dinosaur Behaviors
CHitSpang
Before particles were introduced to the game, there were originally things called 'Hit Spangs'. Basically, they were 3D objects similar to the gun muzzle flashes from the final that would appear upon a bullet making contact with something. While some code for these remains in the final, they cannot be used. However, with the recently leaked Trespasser source code, it is possible to re-enable them. Some pre-release screenshots show them in action, most famously this one found on the back of the box:
Leftover commands:
| Type | Name | Default | Description! |
|---|---|---|---|
| string | A00, A01, ... | Must Specify | SoundMaterials for which the effect is applied. If none is listed, this the default HitSpang. |
| int | SpangCount | Unknown | Maximum number of spangs the effect uses at the same time. |
| float | MinScale | Unknown | Scale factor for minimum size of each spang. |
| float | MaxScale | Unknown | Scale factor for maximum size of each spang. Actual scale will be a random value such that MinScale <= Scale <= MaxScale. |
| float | Decay | Unknown | How much the scale decays in 1 second, in %. 100 means in 1s it has already disappeared. Can take positive or negative numbers. |
| float | ScaleLimit | Unknown | Maximum scale the spangles can take before disappearing. Used for when they grow larger instead of decaying. |
It should be noted that prototype Build 55 uses hitspangs.

Unused Dinosaur Behaviors
A large number of these behaviors were commented out in the source code and others simply didn't get used. The reason why is that if a dinosaur had too many behaviors active at once, it would have abrupt mood swings that would cause it to stand still trying to figure out what to do. As a result, in the retail release, every emotion except Hunger and Anger were lowered to 0. Hunger and Anger were maxed out. This solved the issue, but also made the dinosaurs' goals very single minded. The Emotions also influenced behaviors as can be seen below. The emotions are Fear, Love, Anger, Curiosity, Hunger, Thirst, Pain, and Solidity. The Trespasser CE Executable (which is a source code edit) has an option to enable commented out behaviors.
ActJumpBite
Pretty much what it describes below. The user jumps and takes a snap at the target while airborne.
| Type | Name | Default | Description! |
|---|---|---|---|
| bool | ActJumpBite | false | Not implemented? Leap into the air and bite the target. Not useful, but very cinematic. |
| float | ActJumpBiteFear | -5.0 | Rating feeling, how much the Fear emotion influences in the ActJumpBite activity. Valid range: -10.0 to 10.0. |
| float | ActJumpBiteLove | 0.0 | Rating feeling, how much the Love emotion influences in the ActJumpBite activity. Valid range: -10.0 to 10.0. |
| float | ActJumpBiteAnger | 0.0 | Rating feeling, how much the Anger emotion influences in the ActJumpBite activity. Valid range: -10.0 to 10.0. |

| float | ActJumpBiteSolidity | 0.0 | Rating feeling, how much the Solidity emotion influences in the ActJumpBite activity. Valid range: -10.0 to 10.0. |
ActShoulderCharge
This behavior does just that. The user charges with their body physics box and attempts to do damage. It's similar to the ActRam behavior.
| Type | Name | Default | Description! |
|---|---|---|---|
| bool | ActShoulderCharge | false | Not implemented? The dinosaur hits the target with its body physics box, mostly using the shoulder area. The body physics box needs a damage value. Like Ram, but instead of hitting with the head the user tries to hit the target with their body physics box (or shoulder if lucky). |
| float | ActShoulderChargeFear | -2.0 | Rating feeling, how much the Fear emotion influences in the ActShoulderCharge activity. Valid range: -10.0 to 10.0. |
| float | ActShoulderChargeLove | -1.0 | Rating feeling, how much the Love emotion influences in the ActShoulderCharge activity. Valid range: -10.0 to 10.0. |
| float | ActShoulderChargeAnger | 3.0 | Rating feeling, how much the Anger emotion influences in the ActShoulderCharge activity. Valid range: -10.0 to 10.0. |

| float | ActShoulderChargeThirst | 0.0 | Rating feeling, how much the Thirst emotion influences in the ActShoulderCharge activity. Valid range: -10.0 to 10.0. |
| float | ActShoulderChargeFatigue | 0.0 | Rating feeling, how much the Fatigue emotion influences in the ActShoulderCharge activity. Valid range: -10.0 to 10.0. |
| float | ActShoulderChargePain | -0.5 | Rating feeling, how much the Pain emotion influences in the ActShoulderCharge activity. Valid range: -10.0 to 10.0. |
| float | ActShoulderChargeSolidity | -0.2 | Rating feeling, how much the Solidity emotion influences in the ActShoulderCharge activity. Valid range: -10.0 to 10.0. |
ActOuch
As the name would imply, this is the behavior for pain. This behavior is one of the many commented out behaviors. When a dinosaur is injured, it will make a random sound of pain. Most of the dinosaurs in the retail version have this behavior in their T-script values. However, it's commented out, so it makes little difference to have it.
| Type | Name | Default | Description! |
|---|---|---|---|
| bool | ActOuch | false | Not implemented? Make a sound. Use vocal cube with 'int Vocal = 0'. |
| float | ActOuchFear | 0.0 | Rating feeling, how much the Fear emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchLove | 0.0 | Rating feeling, how much the Love emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchAnger | 0.0 | Rating feeling, how much the Anger emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchCuriosity | 0.0 | Rating feeling, how much the Curiosity emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchHunger | 0.0 | Rating feeling, how much the Hunger emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchThirst | 0.0 | Rating feeling, how much the Thirst emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchFatigue | 0.0 | Rating feeling, how much the Fatigue emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchPain | 5.0 | Rating feeling, how much the Pain emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
| float | ActOuchSolidity | 0.0 | Rating feeling, how much the Solidity emotion influences in the ActOuch activity. Valid range: -10.0 to 10.0. |
ActHelp
Another commented out behavior. It seems to involve calling dinosaurs on the same 'Team' for help. (Team being whatever value the dinosaur is assigned to. Dinosaurs on the same 'Team' will not fight each other regardless of species.) The dinosaur makes a vocalization.
| Type | Name | Default | Description! |
|---|---|---|---|
| bool | ActHelp | false | Not implemented? Make a sound. Use vocal cube with 'int Vocal = 1'. |
| float | ActHelpFear | 1.0 | Rating feeling, how much the Fear emotion influences in the ActHelp activity. Valid range: -10.0 to 10.0. |
| float | ActHelpLove | 0.0 | Rating feeling, how much the Love emotion influences in the ActHelp activity. Valid range: -10.0 to 10.0. |

| float | ActHelpThirst | 0.0 | Rating feeling, how much the Thirst emotion influences in the ActHelp activity. Valid range: -10.0 to 10.0. |
| float | ActHelpFatigue | 1.0 | Rating feeling, how much the Fatigue emotion influences in the ActHelp activity. Valid range: -10.0 to 10.0. |
| float | ActHelpPain | 0.0 | Rating feeling, how much the Pain emotion influences in the ActHelp activity. Valid range: -10.0 to 10.0. |
| float | ActHelpSolidity | 0.0 | Rating feeling, how much the Solidity emotion influences in the ActHelp activity. Valid range: -10.0 to 10.0. |
ActHowl
This behavior was also commented out. Basically the dinosaur roars from the distance, usually lifting its head and opening its mouth a bit.
| Type | Name | Default | Description! |
|---|---|---|---|
| bool | ActHowl | false | Not implemented? Make a sound. Use vocal cube with 'int Vocal = 2'. |
| float | ActHowlFear | -3.0 | Rating feeling, how much the Fear emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |
| float | ActHowlLove | 0.0 | Rating feeling, how much the Love emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |

| float | ActHowlCuriosity | 1.0 | Rating feeling, how much the Curiosity emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |
| float | ActHowlHunger | 2.0 | Rating feeling, how much the Hunger emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |
| float | ActHowlThirst | 0.0 | Rating feeling, how much the Thirst emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |
| float | ActHowlFatigue | -3.0 | Rating feeling, how much the Fatigue emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |
| float | ActHowlPain | 0.0 | Rating feeling, how much the Pain emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |
| float | ActHowlSolidity | 0.0 | Rating feeling, how much the Solidity emotion influences in the ActHowl activity. Valid range: -10.0 to 10.0. |
ActDie
Like ActOuch, this is a T-Script value that most of the Retail dinosaurs have. It's also commented out as well. When a dinosaur dies, it will moan for a bit on the ground. In the case of all carnivores and some herbivores, they'll open their mouth and tilt their head to the side a bit. Presumably, ActDie lasts until the dinosaur hits the 'ReallyDie' state.(which is a value that controls the point where their health won't decrease anymore.)
